DESCRIPTION
     The string functions manipulate strings that are terminated by a null
     byte.

     See the specific manual pages for more information.  For manipulating
     variable length generic objects as byte strings (without the null byte
     check), see bstring(3).

     Except as noted in their specific manual pages, the string functions do
     not test the destination for size limitations.

SEE ALSO
     bstring(3), index(3), rindex(3), stpcpy(3), strcasecmp(3), strcat(3),
     strchr(3), strcmp(3), strcpy(3), strcspn(3), strerror(3), strlen(3),
     strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

STANDARDS
     The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(),
     strcpy(), strncpy(), strerror(), strlen(), strpbrk(), strspn(),
     strcspn(), strstr(), and strtok() functions conform to ISO/IEC 9899:1990
     (“ISO C90”).
